How do I make sure there are no errors in my variable data print run?

Accuracy in a variable data run starts with the data file and ends with a careful proof. Clean input plus a real review of the merge is what keeps errors from multiplying across thousands of pieces.

• Clean the file first: check for typos, duplicates, and inconsistent formatting before you upload.
• Verify the mapping: confirm each column lands in the correct field on the design.
• Review a proof: use the proofing step to see the merge in place before the full run prints.
• Test the extremes: check your longest and shortest entries, since those are where text overflows or looks empty.

Spending a few extra minutes on the proof is far cheaper than reprinting an entire personalized run.
